I cropped this little sketch of Kim out of my brainstorming book. I like how she is slouched in the chair and the way her head is resting on the back of the seat. And I like the little swirl under Kim's lips in the head sketch to the left.
My brainstorming book is full of doodles like these. They usually have something to do with what I'm writing about at the time but not always. This particular doodle was related to a gag I was writing. I was looking for words. See the different words written around the bottom of this sketch? I'll write down every word that kind of means what I'm trying to say because (1) it helps me to spin off other word ideas from the ones I can see (as opposed to remembering them in my head) and (2) it gives me a selection of words to mix and match.
The trouble with sketches like these is that they're very fluid because they're done without purpose and if I decide I want to use the same illustration in my strip, it's very difficult to mimic.
At least, it's difficult for me. Still, they're fun to do because the drawing is so free and relaxed and just goes where it goes. And I have to admit that I think they're fun to look at too.
